nhé bn
mình ko biết
đúng ko
80-[4.52-3.23 ]=210-(x-4)
210- (x-4)=80-24
210 - (x-4)=1024-56
x=968+4=972
mk đg phân vân lm vầy sai hay đúng nên mới hỏi các bn góp ý nha
80 - ( 4.5\(^2\) - 3.2 \(^3\) )
80 - (4.52 - 3.23)
= 80 - (4.25 - 3.8)
= 80 - (100 - 24)
= 80 - 76
= 4
BÀI 1
a, (5 mũ 2 + 1) -9.3 b,80 -(4.5 mũ 2 - 3.2 mũ 3)
c,[(-18) +( -7)] -15 d,(-219)-(-229) + 12.5
a) (52 + 1) - 9.3
= 26 - 9.3
= 16.7
b) 80 - (4.52 - 3.23)
= 80 - (20.25 - 32.768)
= 80 - (-12.518)
= 92.518
c)[(-18) + (-7)] -15
= -25 - 15
= -40
d) (-219) - (-229) + 12.5
= 10 + 12.5
= 22.5
Tick cho mik nhé
tìm x
80 - (4.52 - 3.23)=210-(x-4)
80-(4.25-3.8)=1024-x+4
80-(100-24)=1028-x
80-76=1028-x
4=1028-x
x=1028-4
x=1024
k cho mk nha
Tìm x biết 80-(4.52-3.23)=210-(x-4)
80-76=210-(x-4)
4=210 - x+4 hay x=210
